690WHP on 93 Octane

[Got_M]

I suspect it's a combination of a happy dyno and a yolo tune tbh. I have all those mods + more with an upgraded LPFP, Intake manifold and Omega 65 turbo. Gonna do a hub dyno run on April 23rd and see if i can get close to 620-630ish on 94 octane. This hub dyno reads 7% low.

How'd the dyno turnout? Make any jam on E?

If a bunch of kiddies with too much mom and dad money wanna blow up their turbos/engines because some dude made a one-run kill map for e-points, just let them. Some people only learn how to not "fuck around" when they "find out".

After making 591whp on 94, we loaded the car up with an E47 mix but during the baseline pull all of a sudden the car didn't like the waste gate actuator arm length anymore, pushing the car into limp mode. So it produced a whopping 239.6 whp at 3PSI of boost.

Unfortunately it was too hot to rectify during the dyno session. 2 revisions later at 31PSI the car is doing 5.5s 60-130 though. So it's clearly north of 700 whp DI only.

Fueling:

Precision stage 2.5LPFP
Nostrum injectors
Spool FX400X

Very nice! Stock trans?

Yep. Just a CM1000 twin disc clutch. Ive seen up to 980whp so far on the stock trans. No failures that I know of yet.

Hello,

I saw this car on Instagram equipped with a Pure900 & DI only setup claiming 690whp on 93 octane. Setup and pictures attached.

I'm not doubting the claims nor supporting it, but I am genuinely curious - is this actually possible safely or not? Thank you in advance for any inputs.

Turns out it's pump gas (690 whp) 60-130 times are pretty much identical to mine on pump gas (590 whp). Difference isn't the shift either, transition between 10mph intervals within the gear was similar too.

can you share which fault code you got when the car went into limp mode?

So his dyno is a bit happy? ?‍?

If you look at the dyno chart, it is using STD CF which can inflate numbers quite a bit.

For a car at elevation, it can REALLY inflate the numbers.

STD CF vs No CF:

Did not know that, good explanation!
